Alamo workers found the document in a once-locked filing cabinet that had been forced open. Ultimately, the police were called to investigate.

The Daughters of the Republic of Texas (DRT) — which currently runs daily operations at the Alamo complex — owns two of 13 known original copies of the Declaration and keeps then its own climate-controlled archive next to the Lone Star landmark.

This week, however, DRT officials are learning that one of its smaller chapters may have had a 14th copy . . . that is, a 14th copy some now believe has been carefully stolen by way of a crafty criminal switcheroo.

During a press conference, SAPD chief William McManus said the document in question was uncovered during a recent archival inventory at the offices of the local chapter, which are located at Alamo Plaza. Workers noted that they found it in a once-locked filing cabinet that had been forced open.

Discovered nearby was an empty frame, which once contained what local members always told was a copy of the Declaration. Something was amiss . . . Ultimately, the police were called in to investigate.

McManus explained that archival experts were in the process of analyzing the possibly-fake document found during the inventory, adding, "Quite frankly, we're not sure that anything was stolen at all. It may or may not be a theft."

The drama and confusion comes at a tense time for the DRT, which hopes to renew its operations contract with the state as it prepares to display the priceless “victory or death” letter written by William Barret Travis during the 1836 Battle of the Alamo.
